v0.82.0 — Freestyle bean hopper selection

Added

• Bean hopper selection in Freestyle (dual-hopper Barista TS) (#31). Each freestyle component can now choose its bean hopper. Two new selects — Freestyle Bean Hopper 1 and Freestyle Bean Hopper 2 (hopper_1 / hopper_2) — plus matching blend1 / blend2 parameters on the brew_freestyle service. This makes it possible to brew, e.g., decaf from hopper 2. The selects are shown on a Barista TS (and when the machine type is not yet known) and hidden on a single-hopper Barista T. Previously the hopper byte was hardcoded to hopper 1, so the second hopper was unreachable over BLE.

Fixed

• brew_freestyle service raised HTTP 500 on every call. The service handler passed two_cups as a keyword, but MelittaBleClient.brew_freestyle had no such parameter, raising TypeError. The flag is now a keyword-only argument forwarded to the HE double-brew flag in start_process. The freestyle button (single-cup) is unaffected.
